Marshmallow Spaghetti Tower
Teams race to build the tallest freestanding tower out of dry spaghetti, tape, string, and a marshmallow on top — a classic team-building engineering challenge with a strict time limit.
Paper Tower Challenge
Using only sheets of paper and a length of tape, teams race to build the tallest freestanding tower they can within a time limit — a quick, low-cost engineering icebreaker.
Balloon Tower Building
Teams inflate balloons and stack them into the tallest freestanding tower they can using only tape — a bouncy, colorful twist on the classic engineering challenge.
Bridge Building Challenge
Two teams design and build half a bridge each from craft supplies without seeing the other's work, then join them in the middle to see if they line up — a lesson in planning and communication.
DIY Escape Room Challenge
Hide a chain of homemade riddles, locks, and clues around a room, then split into teams to race the clock solving them in order — a budget-friendly way to run your own escape room without booking a venue.
Plant Care Journaling
Keep a written journal tracking watering, sunlight, and growth of a houseplant or garden plant — sketching leaves and noting changes builds patience, observation skills, and a sense of responsibility.
Lemonade Stand Planning
Design a simple business plan, decide on prices, make a sign, and set up a small stand to sell homemade lemonade to neighbors — a fun first taste of entrepreneurship, math, and customer service.
Letter to Future Self Writing
Grab paper and a pen, and write a letter to yourself to open years from now. Share your summer memories, dreams, and questions — it's a quiet, thoughtful activity that captures who you are right now.
Marble Run Building
Stack tubes, cups, and cardboard tracks into a twisting marble run, then test and rebuild it until the marble makes it all the way down. A hands-on mix of engineering and trial-and-error fun at home.
